Almost first in, baby pair

[Bad Lobster]

20/40 game at the Lobster's favorite undersea grotto. UTG+1 is a regular who's been playing every single hand this session, even though he must know better. BB appears to be new to hold'em and keeps asking questions about the rules. Overvalues his high card hands. No info on SB.

Hero on button picks up 4[img]/images/graemlins/spade.gif[/img]4[img]/images/graemlins/club.gif[/img]. UTG folds, UTG+1 calls, folds to hero.

Hero's play: ?

Normally I'd say an easy raise, but what if I'm virtually guaranteed 2 callers who could have anything?
